sMPs inPUt caPacitor
An external input capacitor is required. This capacitor should be at least 100 µF.
therMal consiDerations
For reliable operation the MP400FC will require a heatsink for most applications. When choosing the heatsink the
power dissipation in the op amp and the SMPS MOSFET switch (Q2) are both considered. The power dissipation of
the op amp is determined in the same manner as any power op amp. The power dissipation of the MOSFET switch
(Q2) is the sum of the power dissipation due to conduction and the switching power.
